Specification of Letters Patent.

Application filed November is, 1908.. Serial no. 453,395.

To all whom it may concern: Be it known that I, FREDERICK H. POM EROY, of Bradford, county of Essex, State of Massachusetts, have invented an Improvement in Gas-Lighters, of which the following is a specification.

This invention relates to a device which is especially adapted to be used in lighting gas, more particularly in gas stoves, but which may be used for lighting any highly inflammable material.

The. object of my invention is to produce a simple and compact device for the above described purpose which willbe capable of being used for a large number of times, and

which is simple, durable and of inexpensiveconstruction. I accomplish this object by the means shown in the accompanying drawing, in which,

Figure l is a side elevation of a device made according to my invention. Fig. 2 is a longitudinal, central sectional view thereof.- Fig. 3 is a bottom plan view, on a reduced scale. Fig. 4 is a cross-section at the line 4-4: of Fig. 2. v of the abrading device. Fig. 6 is a sectional view on line 6-6 of Fig. 2.

As shown in the drawing, a holderis provided which comprises a cylindrical body portion ashaving a flaring or conical-shaped hood, or cup I), connected to the end thereof. A handle 0 is provided with a longitudinal bore 0 in which a rod (Z is inserted, said bore being of greater diameter than the rod throughout the greater portion of its length and being reduced at its inner end so that the rod may be firmly secured to the handle in any convenient manner, as by screw threads d. A shoulder 0 is formed at the end of the larger portion of the bore, which provides an abutment for one end of a coiled spring 6, which is coiled, about the rod The body a is also provided with a cylindrical extension a, which is adapted to fit in the bore 0, so as to-slide freely therein, and both said body and its extension are provided with a central longitudinal bore through which the rod (Z passes and in which said rod is fitted to slide. The spring 6 is of sufficient length to engage the inner end of the extension (1', so that it constantly acts to force the handle upwardly.

A cylindrically shaped abrading'device f,

Fig.5 is a detail view,

consisting of a transversely corrugated steel rod, similar to an ordinary round file, is mounted on the-outer end of the rod d, the latter passing centrally therethrough and having-a headd and a shoulder (Z between which the abrader f is held from longitudinal movement with relation to the rod. The

bore of the body ais enlarged at its lower A flat casing 9, having a sliding cover It on its edge, is mounted on the upper side of the hoodb and the adjacent side of the body a, said casing extending radially with relation thereto, and a pair of guide plates 2' and i are mounted therein, in a position oblique to the bore of said body a, a square, open ended tube being formed which terminates at its lower'end adjacent the lower or outer end of the bore in the body a, and opens at its upper end in the casing.

A sparlcproducing material j, which is a substance composed. of materials such as cerium and alloys of cerium, which, when abraded will emit a number of sparks, is arranged between'the guide-plates'z', i, so that it will slide freely therein and will bear against the surface of the abrader f, and a follower 7c is provided, to bear against the upper end of said material 7', said follower being pressed downward by a coiled spring 172, having two arms m and WP, the arm m being held inv engagen'ient with the follow-er 7c, the arm m being held in engagement with the plate 71, and the spring being under tension to press said arms away from each other. The material j is thus constantly held-against the surface of the abrader f, with a yielding pressure, the force of which is such as to produce the best results, said spring also acting to feed said'material into-' the device is removed from the stove the e and, as the spring yields,.the abrader is forced down to the'dotted position of Fig. 2, so that it abrades' the surface of the material y, with the result that a large number of sparks will be formed and discharged into the hood. As the gas will rise and fill the hood it will instantly become ignited. When springe will at once return the parts to the normal position.

It will be noted that,in the form of my invention shown, while the edge of the hood I is most conveniently employed as an engaging face which, when pressed against the operated by holding one hand and presslng the handle with the" other.

stove by the handle enables the device to be readily operated, yet, that it'may be readily the hood or holder in On account of the mixture of the gas with air before it is ignited, there is a tendency to cause a slight explosion when it is ignited,

- which sometimes even forces back. the gas so that, in a Bunsen burner, it lights back This is prevented by providing perforations in'the hood which will relieve the pressure or permit the gas under pressure to escape therethrough when it is ignited, and also, by

enabled to use the substance almost com pletely, and as the rate at which the sub:

stance is worn away or used is very small the material needs to be replenished only at' long intervals.

As the abrader f is cylindrical in form and is adapted to be rotated, as, well as reciprocated in the holder, the entire surface thereof will be brought into engagement with the material jin the ordinary use of the device, so that the wear will be uniform throughout its surface and the length of time which the abrader will successfullyoperate is greatly increased.

It is not necessary that the device be used in the vertical position shown, as it may be used in any position, in proximity to the burner, the action of the abrader causing the sparks to be thrown for some distance in the direction in which the abrader is forced,

and while the hood is desirable when the device is used as a hand implement, it is unnecessary when the device is fixed in a horizontal posltion to light a single burner in a 3 gas stove.
